SMH5 - VOX Phone

If this feature is enabled, you can answer incoming calls by simply saying a word loudly enough. For example, when you hear a series of beeps for an incoming call, you can answer the phone by saying “Hello” or any other word loudly.

This is enabled from the factory but you can disable this. If this mode is disabled, you have to tap the JogDial or the Phone Button to answer an incoming call.
